This document describes two papers that were presented at the International Conference on Systems, Science, Control, Communication, Engineering and Technology in 2017. The first paper proposes a new audio watermarking technique that embeds watermarks into the extrema of intrinsic mode functions of an audio signal. This embedding is robust against various attacks while maintaining audio quality. The second paper discusses applications of differential equations to engineering problems. It presents techniques for using differential equations to model engineering systems and solve practical problems.

Abstract: In this paper a new adaptive audio watermarking algorithm based on Empirical Mode Decomposition (EMD) is introduced. The audio
signal is divided into frames and each one is decomposed adaptively, by EMD, into intrinsic oscillatory components called Intrinsic Mode Func-tions
(IMFs). The watermark and the synchronization codes are embedded into the extrema of the last IMF, a low frequency mode stable under dif-ferent
attacks and preserving audio perceptual quality of the host signal. The data embedding rate of the proposed algorithm is 46.9–50.3 b/s. Re-lying on
exhaustive simulations, we show the robustness of the hidden wa-termark for additive noise, MP3 compression, re- quantization, filtering, cropping and
resampling. The comparison analysis shows that our method has better performance than watermarking schemes reported recently.

Abstract: Mathematical concepts and various techniques are presented in a clear, concise manner. Various visual features are used to highlight
dirrerent areas. Complete illustrative diagrams are used to facilitate mathematical modeling of application problems. Readers are motivated by a focus
on the relevance of differential equations through their applications in various engineering disciplines. Studies of various types of differential equations
are determined by engineering applications. Theory and techniques for solving differential equations are then applied to solve practical engineering
problems. Detailed step-by-step analysis is presented to model the engineering problems using differential equations from physical principles and to solve
the differential equations using the easiest possible method. Such a detailed, step-by-step approach, especially when applied to practical engineering
problems, helps the readers to develop problem-solving skills.
